Steps to reproduce

1. Create a form that uses useFieldArray, add some mockup fields as default values
2. Call remove on one of the fields
3. Submit the form using the new Form component
4. The FormData still contains entries for the deleted form, just with its contents set to "undefined"

This might be related to some of the options I'm using in my code (e.g. keyName), so check out the codesandbox for that.

Expected behaviour

After removing a field, the previous field should no longer be present in the FormData

What browsers are you seeing the problem on?
